摘要

多孔性材料的發展一直廣被運用於氣體吸附及化工分離程序如變壓吸附與變溫吸附。傳統氣體分離薄膜則分為有機與無機薄膜兩種類別，近年則出現混合基材薄膜(mixed matrix membranes, MMMs)形式將有機高分子基底搭配孔洞材製備，有效提升純高分子薄膜的氣體滲透與分離性能，其中金屬有機骨架化合物(metal-organic frameworks, MOFs)的應用更獲得實驗驗證及關注。本文將介紹近幾年MOF混合基材薄膜的發展及氣體分離應用。

Porous materials have long been used in gas adsorption applications and separation processes such as pressure-swing adsorption and temperature-swing adsorption in chemical engineering. On the other hand, traditional materials for gas separation membranes are categorized into organic and inorganic membranes, with the relatively recent appearance of the mixed matrix membranes (MMMs) where fillers are added to a polymer base to form a hybrid membrane with enhanced permeation and selectivity performance. Of the many fillers, metal-organic frameworks (MOFs) have been experimentally validated and have received increased attention. This article will introduce the development of MOF MMM and its gas separation application.
